Even the most chaotic quantum systems keep a permanent mark of their own past—a "quantum birthmark"—that never fades. Researchers from Tampere University, Harvard University and TU Dresden discovered the feature in their recent study. Their findings shed new light on the elusive relationship between classical and quantum mechanics. Looking ahead, these quantum birthmarks, along with related phenomena known as "scars," could eventually be harnessed to power next-generation nanoelectronics.
Quantum systems never quite forget where they came from
